    It’s a reference to an episode of a 90s sitcom about nothing.

    Specifically the episode of Seinfeld where Elaine finds out that the perfect birth control for her (the sponge) is being discontinued so her new criteria for a sexual partner is to determine whether they’re attractive enough to use one of her limited supply, which she calls being “spongeworthy”.
